Question

7) Find ththe value of (x-y), if 3x+2y=8;
I po
2x+3y=7*
​

Answer 1

Answer:

1

Step-by-step explanation:

On solving the simultaneous equations appropriately we get

x = 2 and y = 1

Therefore the answer (x - y) = 1

Hope this helps.

Answer 2

Answer:10/3,10/2

Step-by-step explanation:((3x+2y=8)*2)-((2x+3y)=7)*3)=0

(6x+4y-16)-(6x+9y-21)=0

-5y=5

y=-1

subsitute y value in first equation

3x+2(-1)=8

3x=10

x=10/3

x-y=10/3-(-1)

Therefore x-y=13/3

if we subsitute y value in second equation we we get 10/3

x-y=(2x+3(-1)=7)

x-y=(2x=10)

x-y=10/2
